Multiple sclerosis (MS) is thought to be an autoimmune disease in which activated T-cells initiate a macrophage mediated destruction of CNS myelin. Bone marrow transplantation (BMT) is currently being evaluated in the treatment of MS in patients with aggressive disease activity. Autologous BMT could potentially reset the immune response to myelin antigens leading to immune tolerance and decreased disease activity. Allogeneic transplantation could reconstitute the immune system potentially arresting the progression of autoimmune disease. The purpose of this paper is to report a patient with MS who underwent allogeneic BMT for chronic myelogenous leukemia (CML) and showed continued evidence of active demyelinating disease by clinical and radiologic criteria over a period of two years. While this is only a single case report with inherent limitations, it suggests that the immune mediated destruction of CNS myelin in MS may not be prevented or aborted by immune system reconstitution, and is consistent with the idea that immune mediated tissue destruction in MS could be targeted against an abnormal antigen.

Eighteen patients with relapse of chronic myelogenous leukemia (CML) after allogeneic bone marrow transplantation (BMT) were treated with recombinant human alpha 2a interferon (IFN). Relapse was defined as greater than 90% metaphases containing the Philadelphia chromosome (Ph) and hematologic abnormalities consistent with chronic-phase (CP) CML. There were 11 males and seven females, with a median age of 38 years (range, 3 to 55). Three patients relapsed after second BMT. Only one patient had received T-cell-depleted marrow initially. The initial IFN dose of 3 x 10(6) U/m2/d was escalated to the maximum tolerated dose or to a maximum of 6 x 10(6) U/m2/d. IFN controlled the white blood cell (WBC) counts in 14 of 16 patients who had abnormal counts, and in all six patients with an elevated platelet count. Six patients (33%) have had a complete disappearance of the Ph and two have had a partial response (less than 35% Ph+ metaphases). One patient has a decrease in Ph+ metaphases after 9 months of IFN. Five patients had no significant cytogenetic response after 9 to 12 months, and four developed clinical accelerated phase or blast crisis after 3 to 6 months on therapy. Of four patients with a sex marker, the Ph- population was of donor origin in three and of host origin in one. Clonal cytogenetic abnormalities other than Ph were present in 13 patients and did not predict for lack of response to IFN. IFN is effective in suppressing the Ph clone in some patients who relapse with CML after allogeneic BMT and controls the blood counts in the majority.

Abstract The influence of interferon- (IFN) pretreatment on the outcome after allogeneic bone marrow transplantation (BMT) in chronic myelogenous leukemia (CML) is controversial. One goal of the German randomized CML Studies I and II, which compare IFN ± chemotherapy versus chemotherapy alone, was the analysis of whether treatment with IFN as compared to chemotherapy had an influence on the outcome after BMT. One hundred ninety-seven (23%) of 856 Ph/bcr-abl–positive CML patients were transplanted. One hundred fifty-two patients transplanted in first chronic phase were analyzed: 86 had received IFN, 46 hydroxyurea, and 20 busulfan. Forty-eight patients (32%) had received transplants from unrelated donors. Median observation time after BMT was 4.7 (0.7 to 13.5) years. IFN and chemotherapy cohorts were compared with regard to transplantation risks, duration of treatments, interval from discontinuation of pretransplant treatment to BMT, conditioning therapy, graft-versus-host disease prophylaxis and risk profiles at diagnosis and transplantation, and IFN cohorts also with regard to performance and resistance to IFN. Outcome of patients receiving related or unrelated transplants pretreated with IFN, hydroxyurea, or busulfan was not significantly different. Five-year survival after transplantation was 58% for all patients (57% for IFN, 60% for hydroxyurea and busulfan patients). The outcome within the IFN group was not different by duration of prior IFN therapy more or less than 5 months, 1 year, or 2 years. In contrast, a different impact was observed in IFN-pretreated patients depending on the time of discontinuation of IFN before transplantation. Five-year survival was 46% for the 50 patients who received IFN within the last 90 days before BMT and 71% for the 36 patients who did not (P = .0057). Total IFN dosage had no impact on survival after BMT. We conclude that outcome after BMT is not compromised by pretreatment with IFN if it is discontinued at least 3 months before transplantation. Clear candidates for early transplantation should not be pretreated with IFN.

PURPOSE Allogeneic bone marrow transplantation (BMT) is an option for some patients with chronic myelogenous leukemia (CML). We retrospectively evaluated the effect of various risk factors observed at diagnosis and at transplantation on survival, event-free survival (EFS), and relapse after BMT. PATIENTS AND METHODS Seventy-nine patients with CML in chronic phase (CP) were treated with cyclophosphamide and total body irradiation followed by BMT. Graft-versus-host disease (GVHD) prophylaxis consisted of cyclosporine (CsA) in most instances or CsA plus the use of lymphocyte-depleted bone marrow (BM). RESULTS Survival at 4.5 years was 52%. Stratified by age and GVHD prophylaxis, the actuarial survival was 65% (95% confidence interval [CI], 47% to 78%) in patients aged less than 30 years receiving unmanipulated BM, 33% (95% CI, 12% to 56%) in patients greater than or equal to 30 years old receiving unmanipulated BM, and 38% (95% CI, 14% to 63%) in patients greater than or equal to 30 years old receiving lymphocyte-depleted BM. In univariate analysis, patient age (greater than or equal to 30 years) and the use of lymphocyte-depleted BM negatively influenced EFS. When stratified by age and GVHD prophylaxis, however, ABO incompatibility, cytomegalovirus (CMV) seropositivity, and chronic GVHD significantly reduced the probability of EFS. Factors that have been associated with early death in nontransplanted patients (ie, sex, spleen size, blast and platelet counts at presentation) were not predictive of long-term survival outcome after BMT. CONCLUSIONS The data suggest that (1) BMT should be offered early after diagnosis to all patients with CML in CP who have compatible sibling donors regardless of prognostic factors at presentation, (2) GVHD remains the principal cause of mortality after BMT in patients receiving CsA, and (3) T-cell depletion by the physical separation method of counterflow elutriation (CE) is associated with a significant risk of relapse.

PURPOSE This study was conducted to assess the comparative values of allogeneic bone marrow transplantation (BMT) and autologous bone marrow transplantation (ABMT) with sequential postremission chemotherapy (SPC) in children with acute myelogenous leukemia (AML) in first remission. PATIENTS AND METHODS From March 1987 to March 1990, 161 assessable patients younger than 15 years of age with newly diagnosed AML were treated uniformly with two courses of daunorubicin and standard-dose cytarabine. After initial consolidation with a course of daunorubicin, cytarabine, and thioguanine (DAT), patients in complete remission (CR) were randomized to receive either ABMT or SPC, except for those with an HLA-matched sibling who were assigned to undergo BMT. SPC consisted of three additional courses of DAT, followed by three pairs of drugs administered sequentially for a total of six cycles. RESULTS Overall, 127 of 161 patients attained CR (79%). The estimated probabilities of survival and event-free survival (EFS) at 5 years for all patients were 42% and 25%, respectively (median follow-up, 28 months). For the 127 complete responders, the 5-year probability of disease-free survival (DFS) was 31%, with a cumulative risk of relapse of 64%. For the purpose of this study, all complete responders were evaluated for analysis of disease outcome according to the intent-to-treat principle, regardless of whether they actually received the intended therapy. The 5-year DFS was 51% for the BMT group (n = 24), significantly higher (P = .03) than that observed for the other cohorts: 21% for ABMT (n = 35), 27% for SPC (n = 37), and 34% for a group of 31 nonrandomized (NR) patients. Bone marrow relapse was the most frequent cause of postremission failure in all therapeutic subgroups, including the BMT cohort, in which no deaths attributable to the toxicity of the procedure were recorded. CONCLUSION The results of this study show that BMT is more effective than ABMT or SPC in preventing leukemia relapse and extending DFS duration in children with AML in first remission.

Abstract Eight patients with Ph1-positive chronic myelogenous leukemia (CML) in chronic or accelerated phase received high-dose cyclophosphamide, total body irradiation, and bone marrow transplantation from an HLA-identical sibling donor. All patients had prompt engraftment and achieved complete hematologic remission. Six patients remain alive and in continuous remission with a normal bone marrow karyotype 3–20+ mo posttransplant. One patient died from cytomegalovirus interstitial pneumonitis. Only one patient who was transplanted in accelerated phase relapsed 6.5 mo posttransplant and died in blast crisis. High-dose combined modality therapy is capable of producing sustained complete remissions in patients with CML treated during chronic or accelerated phase.

Abstract Allogeneic bone marrow transplantation (BMT) is the only curative therapy available for patients with myelodysplastic syndrome (MDS). In an attempt to identify prognostic factors influencing outcome, we collected data retrospectively on 60 consecutive adult patients who had undergone BMT at our center for primary MDS or acute myelogenous leukemia evolving from preexisting primary MDS (sAML). Patients were divided into subgroups according to cytogenetic abnormalities based on a recently described International MDS Workshop categorization system. The 7-year actuarial event-free survival (EFS), relapse rate, and nonrelapse mortality (NRM) for all patients were 29% (95% confidence interval [CI], 16% to 43%), 42% (CI, 24% to 67%), and 50% (CI, 37% to 64%), respectively. The EFS for the good-, intermediate-, and poor-risk cytogenetic subgroups were 51% (CI, 30% to 69%), 40% (CI, 16% to 63%), and 6% (CI, 0% to 24%), respectively (P= .003). The corresponding actuarial relapse rates were 19% (CI, 6% to 49%), 12% (CI, 2% to 61%), and 82% (CI, 48% to 99%), respectively (P = .002) with no difference in NRM between the subgroups. Univariate analysis showed cytogenetic category, French-American-British (FAB) subtype, and graft-versus-host disease (GVHD) prophylaxis used to be predictive of relapse and EFS. In multivariate analysis, only the cytogenetic category was predictive of EFS, with the relative risk of treatment failure for the good-, intermediate-, and poor-risk cytogenetic subgroups being 1.0, 1.5, and 3.5, respectively (P = .004). For adults with primary MDS and sAML, even after BMT, poor-risk cytogenetics are predictive of an unfavorable outcome; novel treatment strategies will be required to improve results with allogeneic BMT in this patient population. © 1998 by The American Society of Hematology.
